ABOUT OUR COVER
This issue’s cover of a Cope’s Gray Treefrog (Hyla chrysoscelis) was taken in St. Charles , Illinois by Ed Reschke. There are two species of Gray Treefrog that are identical in appearance: Cope’s Gray Treefrog and the Gray Treefrog (Hyla versicolor). Since their ranges overlap extensively (eastern U.S. and southernmost Canada ), it is very difficult to distinguish them based on size, coloration, or habits. However, it is often possible to identify them while they are calling in the spring. Positive identifications require blood sampling and laboratory analysis. The Cope’s Gray Treefrog is a diploid species, whereas the Gray Treefrog is a genetic tetraploid.

Reschke photographed this Cope’s Gray Treefrog on a former colleague’s property with a very nice wetland. He used a Nikon F5 camera, a 200mm o lens, and Fujichrome Velvia film.
